Over 900 species of trees, some indigenous to the Pacific Northwest, others imported from around the world, are found in the hills and meadows of the 175-acre arboretum at the south end of Washington Park. Trails wind through well-established stands of magnolias, maples, oaks, hawthorns, cherries and the most extensive conifer collection in the US. The short Overlook Trail just south of the Washington Park light-rail station leads to the visitor center (you can also drive there) where you'll find maps and booklets for self-guided tours. Bristlecone Pine Trail off Fischer Lane is a 1mi paved trail with handicapped access parking. The Vietnam Veterans Living Memorial, dedicated in 1987, lies at the southwest corner of the arboretum, just above the World Forestry Center. From a central bowl-shaped area an ascending walkway spirals up to six black Indian granite markers inscribed with the names of Oregonians reported as dead or missing from 1959-1976. In the middle of the garden a granite plaque reads, "So long as we are not forgotten we do not die. And thus this garden is a place of life".
